Forecast Discussion & Concerns
Rainfall chances are much lower today, tonight, and much of Saturday but rain will likely return by Saturday night (at the latest). Hopefully, the better rain chances will hold off until after the Crossville Christmas parade. That parade begins at 4:30 Saturday.
By next week, a strong cold front will blow through on Wednesday. That will usher in colder and drier air, as it looks right now.
The Storm Prediction Center outlook for severe weather shows severe storms possible on Wednesday associated with that frontal passage across the South, but they currently keep the greatest threat south of our area (pictured below). Based on the current forecast data, that certainly seems reasonable. I’ll monitor that closely in the coming days.
HRRR Radar Model
This model begins at 9:00 a.m. and ends at midnight, in one-hour increments. Showers are expected to be much more isolated today.
